IMPROVEMENT IN BUTTER-TU BS.

Specification forming part of Letters Patent No. 206,051, dated July 16,1878; application filed May 7, 187e.

To all whom it may concern:

Be it known that I, LAUREN STONE, of Dryden, Tompkins county, New York,have invented an Improved Butter-Tub and Return- Pail, whereof thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to covers for tubs or rkins or pails that areeasily opened and closed for the various uses which such tubs or pailsare applied to; and the nature of my invention will be apparent as Idescribe it.

Figure l is a sectional elevation of my tub, showing its construction.Fig. 2 is a view of the top of my tub. Fig. 3 is a View of a top of thetub, with its upper portion made in a skeleton form.

In the figures, it will be seen that the cover proper is composed of twoparts or halves, b b', which have a blank space for the purpose ofallowing the two parts to be put in the tub so that the tongues orbeveled edges shall enter the chine or croze cut in the tub near itstop. This space between the two halves of the cover is lettered c, andwhen the tongues or beveled edges of the parts b b are properly adjustedby means of this open space c, the parts b b are on their top surfacesflush or level with the top of the staves of the tub. Next comes thenecessity that the space c be covered, and that the parts b b be heldfirmly in the chine or Croze; and my method of doing it is to cover thespace c by a flat piece of wood, c, and thus the necessity of coveringthe open space c is met, the piece e extending also over the tops of thetub-staves, and thus making a close joint at the ends of the space c.

To hold the parts b b in place, I put on or over the parts b b' twoother parts, (marked a a', Fig. 1,) and make them fast to the parts bbf-namely, the part a to the part b, and the part a' to the part b.These parts a a lap over the tops of the staves of the tub or frkin, andserve various purposes: First, the lapping just spoken of, wheninserting the cover, by resting on the top of the staves, guides thetongues on the edges of b b' into the chine or croze cut in the top ofthe tub; second, they prevent warping of the parts b b; third, the partsa a', by being cut, as shown, with beveled or tongued edges next to thepiece e and to it that piece, hold that piecefast, and the parts b b bytheir edges in the chine cut in the top of the tub; fourth, as the piecec is cut wedge-shaped, and is thus a wedge or key, it acts on the partsa a', so as to lock the parts b b' and the parts a a' to the tub,firkin, or pail, as has been said, and as is shown in the drawings or,in other words, I make the parts a a fast to the parts b b', and soshape the straight edges of the parts a a.' a little way from the openspace c that the wedge e shall bear on the parts a a', and thus thrustthe outer edges or tongues of the parts b b into the chine or Croze cutin the top of the tub, in the manner shown.

Fig. 3 is a top of a cover, with the parts c a made in skeleton form. Inall its uses and functions this skeleton form corresponds to the formshown in Figs. l and 2, and is equivalent to the parts a a shown inthese figures. The various parts of the skeleton form are marked a" a'",which refer to the same parts as lettered a a in Figs. l and 2, and maybe made of the exact form shown, or of similar forms.

The wedge or key e is the same, the mode of locking and use of the keyis the same, as are all the parts of the skeleton in its uses, as I havejust said. v

The skeleton form allows of the ready use of the rod f through theWedge, and the parts of the skeleton next the wedge, and the use of thepadlock, as shown in Fig. 3.

Two forms of the edges of b b and the wedge e are shownone simplebeveled edges, the other tongued edges 5 and in the iirst case the crozeor chine is cut with a groove simply beveled, and in the other case thecroze or chine is cut with a groove to fit the tongue.

The same is true of the two forms of edges for the wedge.

The handle d is useful when tubs, flrkins, or pails are to be returned,as well as for the Various usos nml pnrposvs to whith the tllh, lilkin,0I' [mil muy hv applied.
